Having a very puzzling problem with FirewallD and one single vps instance I have. For some reason it appears everything showing within Webmin/Networking/FirewallD is not matching the actual config at /etc/firewalld. Additionally the webmin interface does not look to be communicating at all as it shows it is not running while it actually is. Since I have nine other servers none of which ever had this issue but did a full OS reinstall and ended right back with the same exact issue I suspect something wrong or weird about the hosting companies master image but three fresh installs and all three resulted in this same issue. The firewall is running, dos commands are all working. It is almost as if the real operating firewall and the config being accessed by webmin/virtualmin are not the same files.

Operating system CentOS Linux 7.6.1810
Webmin version 1.900 Usermin version 1.751
Virtualmin version 6.06 Authentic theme version 19.32-beta3
Time on system Sunday, June 16, 2019 7:02 PM Kernel and CPU Linux 3.10.0-042stab134.7 on x86_64

Not sure where to start to get the two to communicate.
